How is Amino Trimethylene Phosphoric Acid (ATMP) Produced?

The production of Amino Trimethylene Phosphoric Acid (ATMP) is usually a several-step process. The process is usually carried out using formaldehyde, phosphoric acid and ammonia. The following steps usually follow this process:

Oxidation of Formaldehyde: Formaldehyde is reacted with hydrogen peroxide, an oxidising agent, to produce formic acid.

Addition of Phosphoric Acid: Formic acid is reacted with phosphoric acid. During this reaction, high temperature and low pH levels are used. In this step, Trimethylene Phosphoric Acid (TMPO), the precursor of ATMP, is formed.

Amidation of TMPO: TMPO is reacted with ammonia and ATMP is produced. In this step, one hydrogen atom of TMPO is displaced by ammonia and the end product ATMP is obtained.

ATMP production can also be realised by direct reaction of phosphoric acid and ammonia. However, this method is generally less widely used.
